Linpack benchmarks in Fortran for Sun SPARC systems

The following table collects performance results for the
double precision (64-bit) Linpack benchmark program in
Fortran using the native Sun Fortran compiler, f77
version 4.2, on Sun Solaris 2.5 and 2.6.

Three optimization levels are tested, and their relative
performance is exhibited.

The lowest optimization level is -g, for debug
compilation.

The second level is -O, for normal optimization.

The third, and last, level is -O5 -dalign -libmil -cg92
, which selects maximal optimization, allows use of
doubleword loads and stores, allows inlining of small
procedures, and selects the code generator for SPARC Version
8 (1992), which provides integer multiply in hardware. For
brevity, the column header in this case is abbreviated to
just -O5.
